To all whoml it may concer/1r:

Be it known that we, Gus'iavn GIN, ci Paris, France, and VICTOR CoUR'rnoUissE, ot' Lille, France, both citizens of thc Republic ol' France, have invented certain new and useful Improvements in Electric Processes lor Gassing Threads, ol' which the following is a full, clear, and exact specification, reference being had to the accompanying drawing, showing an elevation of parts oi' an apparatus by aid of which our said process may be source of electrical energy, not shown so that a current maybe )assed theretlnough to heat said member as desired, s is the thread supported, tensioned, and propelled on reels diagrammatically indicated at w, w, and rota tively supported by any convenient means, not shown, to insure substantial alinement of the thread with the central longitudinal axis of said member. A blower apparatus is provided comprising a blow pipo nozzle p, haw ing connection p with an air compressor, not shown, valve pt and means 'p3 lor movably supporting said nozzle. 'lhe member g is constiicted, or reduced in section at y proximately to the )oint at which the jet ci air from said nozzle is injected into said membei'. This vformation insures, as er Joulcs law, a higher temperature in mem )er g at its said )oint ol' constriction, thus compensating for tire cooling ell'cct of the jet.

Our process is worked as follows: The current being turned on, member y becomes heated to the required temperature and the electrically heated heat radiated therefrom singes the tendrils oi the thread which is sinndtaneously pro pelled through said member by rotation oi` the reels. r lhc singeing, however', in many cases, particularly where woolen threads are involved, cannot be sulliciently perfectly eil'ected because of lack of oxygen, the valve p2 is in such eases opened to the extent required and the nozzle p disposed and adjusted to inject into the heated member g and proximately to the thread, `a blast cil air, or other gas containingr oxygen. The presence of the extra supply ol' oxygen thus allordcd enables the singeing to be completely and perfectly accomplished. The blast also simultaneously expels from the tubular member undesira ble products ot' combustion of the librils.

lt will be understood that we do not conline ourselves to the particular apparat-us shown .for the purpose otpracticing our roccss which consists broadly in singcing ol the undesired librils by uoximity to electrically heated surfaces, in tire presence ol more oxygen than is supplied by the surrounding atmosphere under normal conditions.

llaving thus described our invention, what we claim as new and desire to secure by liet ters Patent isz"d4 1. The process ol gassing threads which comprises singeing them by proximity to electrically heated surfaces in presence of more oxygen than is supplied under normal atmospheric pressures.

'ille process ot' gassing ythreads which comprises singcing thorn by proximity to surl'accs and simultaneously subjecting said surfaces and thread to an air blast.

ln testimony whereof, we have hereunto set our hands in presence of two witnesses.
